COIN-ACTUATED LOCK.

Application filed January l5, 1923.

.To all iii/icm t may concern,

lle it known that l, ilosnrii Burioni, a citizen oil" the United hltates, residing,` at Kansas lli in the county oit Jackson and State ot lvlissouri, have invented certain new und use'tul Improvements in loiii-rictnatcd Locks; and l do declare the following to be a full, clear, and exact description oli the invention,v such as will enable others skilled in the art to which it app ins to inalie and use the suine, reilerenee being had to the :iceoinpanying.d rawingrs, und to the Vigures of reference niarked thereon, which forni u port oil? this specification.

This invention relates to locks and particularlv to a lock which normally can be operated only 'troni the outside and only upon the insertion oi a coin, check or token o'l deterr ined value. The loch' is constructed, however, that 'it may he unlocked lroni the inside alter the coin, check or token hi .ieen intrmluced by the turning olf the knob trein the ii i This operation cruises the lock to be f' it to reestablish the coin-actuated ,un ready to function upon the introduction ol another check, coin or token.

'..lhere also ineens whereby :in attendant con operute the lock it'roin the outside without iiisertingl a token and there is additional ineens whereby the lock can be operated :troni the outside by u inir a special key.

rlhe lock is especially designed :tor application to booths in comfort stations and priniurily belongs to the general class known as toilet door locks. lt embraces means for automatically lockinp; the holt against actuation it'roni the outside when the door is closed hut not uuainst operation 'troni the inside. lit einbruccs a counter or registering,r incollanisin which functions only when a token or coin oil? proper denomination passes through the niechenisui, the counter or registering` uuchzinisin being such that it will not lo i when the custodi-anis or attendanth l.` used, nor will 1t lunction 'when the other key known as a manager-ls key is used.

fl't also includes a signal to indicate whether o not the hooth is occupied und it conteurn putes other novel features, all oli which will he speciiically reitcrred to hereinalter, reiterenee heinfr had to the accoinptoying` drawings, in which llip. lA is a perspective view ot a lock con structed in accordance with iny invention,

llig. ll is an elevational view of the bolt, the tumbler, the throw lingers and the inechanisin operated by the 1nanage1"s key viewed from the liront, showing the bolt projected.

lling. l2 is a siniilar view oi the bolt, the tumbler, the coin release showingl the bolt retracted.

llig. ll is an elevational View ot' part of the bolt, the throw fingers, the coin release und the coin chute, the coin release being shown in releasingl position.

Fig. lilis a like view showing` the coin release supporting the coin or token, the coin chute being shown in section.

'.llhe lock case or housing is shown as a vertically elongated shell l, having at its upper end two slots 2 and 3, the lirst being` a signal slot and the second a coin slot. ln Vthe liront wall oil the case is an opening Ll, adapted to be closed by a cover plate or door 5, having at its upper edge a projecting oltset lip or flange 6, to engage the upper edge of the opening,i Ll, the lower end oit the cover plate being; fastened by a locking lug` 'l' engaging a slot 8 in the keeper plate 9, fastened to the interior of the case. The locking lug is adapted to be controlled by a lock l0 of appropriate construction, the lock being operated by a keyll. When the cover plate is removed, access can be had to the bottom o1 the case to ieinove the coins which have been deposited therein.

The main lool; carrying trame is shown as consisting ot three substantially parallel plates designated 12, 13 and 141, a ranged from the front to the back in the order named. The intermediate plate 13 supports the remaining plates and the entire trame is secured in an appropriate manner within the case. The plate 13 carries a coin chute 15, the inlet end 16 ot which registers with the slot 3 so that the coin, checl: or token, 11ereinafter referred to a coin, can be introduced into the coin chute so that it may pass 'through to be intercepted by the coin-actuated mechanism.

Below the coin chute are two coin detent levers 17 and 18, pivoted to the plate 13. The toe 19 ot' the lever 17 and the curvec-L face 2O ot the lever 18 are in spaced relation but the space between. them will normallyY be such as to prevent the passage o? the coin until the bolt is withdrawn. The toe 19 of the lever 17 is normally in the position shown in F ig. 13. v'hen the coin drops :trom the chute 15, it will contact with the toe of the lever 17 and cause it to nieve downwardly to the position shown in Fig. 14 so that the coin will at irst be held in the position shown in Fig. lei. As the toe of the lever 17 moves downwardly, its heel 21 will be raised, carrying with it a pivoted register-actuating dog 22, the toe 23 et which may move into position to be engaged by the longitudinally movable bolt 24, which is to be actuated by `mechanism to be hereinafter described.

rlhe heel 25 oit the dog will be in position to contact with a lateral tinger 26 on the spindle 27 of a register .23 so that when the bolt is withdrawn and the dog 22 is 'rocked by Contact of the end ot the bolt with the toe 23, the finger 26 will be swung about the axis ot the spindle 27 and register one coin. The construction ot the register per so constitutes no part oi? the present invention; sui'lice it to say that there is a return spring in the case of tl' ene registerl 28 to return the finger to normal position after it has been actuated.

rEhe movement of the bolt to unlocking position will throw the coin dctent or lever 18 about its pivot 29 beca e the heel 30 ot the lever 18 engages a notch 31 in the bolt. rliher'etore, the withdrawal of the bolt will be etlective in widening the distance between the toes 19 and 20, permitting the coin, check or token designated 32 to drop into the bottom of the case 1.

As soon as the weight ot' the coin 32 is taken oft the toe ot the lever 17, the lever will re-assume the position shown in Fig. 13. rThe bolt 2li is urged outwardly into keeper-engaging position by a spring 33 which is carried by the plate 13. The bolt can be tracted by either ot two throw levers or tingers 311- or rlhe finger 34 is carried by the spindle 36 integral with the outside knob rlhe spindle 36 has a centrai longitudinal opening or key-passagew ay 38 extending entirely through it for the introduction of the custodians ley 39, as will be explained more in detail hereinafter. l{".f'vhen the spindle 3G is turned, the throw inger 35i is turned so that it will press ainst the boit-act ating lever 10, pivoted tace of the plate 13 by a pivot 41, which ei; ends through the plate 13 and support similar to the loyer 110, the fl however, by the ever on the hub i3 supported in and adapted to be operated only iob on the inside spindle or by the hey 3i), hich adapted to entend through the ol Aing and engage the crcss pin L16, carried by the hub. The outside ini-ob cannot be turned, however, til certain releasing devices are operated; when the coin has passed through d b en deposited on the toes L a le er le". er being actuated, throw 4 that 'unless a coin is deposited, the tur ing ol' the Knob cannot rock the o ger 3e because the lateral moveci the lower portion oi the lever Li0 will be opposed b v the ii p. iilhen the coin is deposited, how' so to depress the will be raised high hugs the hub for the s uw' I /vx-b r 1 1 linger 3st. fnererore, when tne coin nas deiiessed the toe 19 oi the lever 17 and the lip li8 has moved the position shown in Fig. 12, it is obvioiEN that the rocking linger can aetuate rocking lever il0, withdrawing the bolt which is supported by a lug carried by the plate i3 and projecting through the slot in the bolt. ris the bolt is retracted by reason of the tact that the lower end of the rocking lever Li() engages the lateral extension or shoulder 5st on the end or the bolt 24, a signal operating linger will be swung so that its projecting end will swing the arm :'37 about the pivot 53 plate 12.

Since the arm 57 carries a signal segment or blade 59, on which indicia is placed, the blade in its original position will indicate that the booth is vacant.
